The Advertising Standards Authority has not upheld complaints relating to two out of three statements in a Conservative Party pamphlet critical of Labour's Napier candidate, Stuart Nash.
Mr Nash's campaign manager, Robert Johnson, complained to the authority about the pamphlet, which compared Conservative policy to the stance taken by Mr Nash on several issues.
The pamphlet was distributed in the Napier electorate where Mr Nash is vying for the seat against Conservative candidate Garth McVicar.
In a decision released yesterday, the authority said the Conservative Party had acknowledged it had made an error in the pamphlet by stating Labour had voted with National in 2012 " to remove Napier's right to vote independently on [the local government amalgamation] issue".
The authority said it considered the matter "settled" because Mr McVicar had apologised to Mr Nash for the error and inaccurate brochures had been destroyed.
